GitHub recently published this repo SpecKit， an open-source toolkit to fix a big weakness of vibe coding： that AI often starts coding before the product rules are clear.

It turns vibe coding from "ask the AI to build it" into "write the product spec first， then make the AI build from that spec."

Most AI coding today starts with a loose prompt， then jumps straight into code， which often produces working demos but weak requirements， missing edge cases， and messy rework.

Spec Kit pushes the process the other way： first define what the product must do， then clarify gaps， then create a technical plan， then break that plan into tasks， then let the agent implement against those written artifacts.
